Ansley, whose hiring was first reported on footballscoop.com, has been serving the same role at Alabama. Singleton, who had been running backs coach with the Indianapolis Colts, was reported by NFL Media.

In addition, the Raiders will interview Dave DeGugliemo for the position of offensive line coach, according to NFL Media. DeGuglielmo was most recently the line coach at Miami but also was Bill Belichick’s line coach in New England in 2014-15.

Mike Tice has been the Raiders line coach for the last three seasons under Jack Del Rio.

Jim O’Neil, a former defensive coordinator for the 49ers and Cleveland Browns, will interview for a position on the Raiders defensive staff, Adam Caplan reports.

At the press conference announcing his hiring, Gruden said he had filled all three coordinator positions with Greg Olson (offense), Paul Guenther (defense) and Rich Bisaccia (special teams).

None of the assistant coaching positions have been confirmed by the Raiders.

One name to keep an eye on — Sanjay Lal, a former Raiders wide receivers coach who served in that capacity with the Colts.

Lal was a Raiders quality control coach in 2007-08 and coached wide receivers in 2009-11.
